A High-Resolution Clock Phase-Shifter in a 65 nm CMOS Technology
The design of a high-resolution phase-shifter which is part of the LpGBT, a low power upgrade of the gigabit transceiver (GBTX) for the LHC upgrade program, is presented. The phase-shifter circuit aims at producing a programmable phase rotation (up to 360°) with a time resolution of 48.8 ps for several input clock frequencies: 40, 80, 160, 320, 640 or 1280 MHz. The circuit is implemented as two functional blocks: a coarse phase-shifter, with a fully digital implementation, and fine phase-shifter, based on a Delay-Locked Loop (DLL). The post-layout simulations show that the peak-to-peak values of INL and DNL are 0.1 and 0.06 LSB (48.8 ps) respectively at 1.28 GHz in the nominal corner while at 40 MHz the values are 0.06 and 0.05 LSB respectively. The phase-shifter has been designed as a radiation-tolerant circuit by means of enclosed layout transistors (ELT) in a 65 nm CMOS technology to achieve high resolution and reduced power dissipation. The typical power dissipation of the fine phase-shifter at the lowest and the highest frequencies are 1.1 mW and 9.1 mW respectively at 1.2 V supply voltage
28.6 A 78.5dB-SNDR radiation- and metastability-tolerant two-step split SAR ADC operating up to 75MS/s with 24.9mW power consumption in 65nm CMOS
High-resolution, low-power radiation-tolerant ADCs are under great demand from medical, aerospace and high-energy physics applications. In the ATLAS Liquid Argon Calorimeter of the LHC experiment at CERN, the radiation operation condition coupled with the large dynamic range (>12b ENOB), 40-80MS/s sample rate and low power (for cooling system requirement) specs [1] make the design of such ADCs a very challenging task
The Cryogenic Performances of Specific Optical and Electrical Components for a Liquid Argon Time Projection Chamber
AbstractIn this paper we present a cryogenic performance study of specific optical and electrical components for the Liquid Argon Time Projection Chamber (LArTPC), a potential far site detector technology of the long baseline neutrino experiment (LBNE). We have confirmed that an LVDS driver can drive a 20-meter CAT5E twisted pair up to 1 gigabit per second at liquid nitrogen temperature (77 K). We have verified that a 16:1 serializer Application Specific Integrated Circuit (ASIC), three types of laser diodes, optical fibers and connectors, and field-programming gate arrays (FPGAs) continue to function at 77 K. A variety of commercial resistors and capacitors have been tested at 77 K. All tests we have conducted show that the cold front-end electronics is promising
